Collimation Dial
Two Collimation Dials X and Y are provided to adjust the light axis.
Look into one of the Collimation Holes provided above the lens to collimate
the opposed unit. Turn the Collimation Dial, until the opposed unit can be
seen in the center of the hole.
Vertical adjustment
Turn the Collimation Dial Y to adjust the light axis in a vertical direction.
The degree range of movement on “Y” dial is plus-minus 10 degrees. One
full turn of dial corresponds to approximately 1 degree change.
Horizontal adjustment
Turn the Collimation Dial X to adjust the light axis in a horizontal direction.
The degree range of movement on “X” dial is plus-minus 10 degrees. One
full turn of dial corresponds to approximately 1.7 degree change.
Adjustment procedure
1.Adjust the light axis of the Transmitter.
2.After the light axis adjustment is completed, close the main cover
immediately.
3.Adjust the light axis of the Receiver.
4.After the light axis adjustment is completed, adjust the receiving light
intensity next.

〇Ensure that the cover of the Transmitter is closed completely
before adjusting the receiving light intensity.
If the cover is opened, it is not possible to adjust the receiving light
intensity.
1.Confirm that the control panel is powered off (i.e. the Detector is
not powered).
2.Open the cover of the Receiver, and move the Status Switch from
“NORM” to “CAL” position.
3.Turn on the power of the control panel to power the Detector.
Confirm that the Alarm Indicator of Receiver blinks.
4.Set the Distance Selection Switch according to the table below.

In spite of adjusting the Light Intensity Adjustment Volume to
maximum, if the orange indicator still blinks, the adjustment of light
axis or the setting of Distance Selection Switch may be
inappropriate.
Check the adjustment of light axis and the setting of Distance
Selection Switch.
In spite of adjusting the Light Intensity Adjustment Volume to
minimum, if the red indicator still blinks, the setting of Distance
Selection Switch may be inappropriate.
Check the setting of Distance Selection Switch.
6.Confirm that received light intensity level is adjusted (i.e. only the
green indicator is blinking). Put the Status Switch back to the
“NORM” position, and the adjustment of received light intensity is
completed. Close the cover immediately after the completion.
7.When the Status Switch is back to “NORM” position, the Detector
starts its initialization that takes 3 minutes. The Alarm Indicator of
the Receiver blinks during the initialization. The indicator turns off,
when the initialization completes and the Detector goes back to
the normal monitoring condition.

8.After adjusting the Detector, the state of detector can be
monitored by using the Remote Station for Beam Detector. For
the details of monitoring, refer to the instruction manual of
Remote Station for Beam Detector LP04/ LP05.
〇Make sure that the voltage between K and C during monitoring is
within the following range, and not the range specified in the
instruction manual of the Remote Station.
Voltage range for monitoring
Approx. 2.08V to 2.23V
〇If the main cover is left open longer than 10 seconds after the Status
Switch has put back to the “NORM” position, put the Status switch
back to “CAL” position and perform the operation from 5. above again.
〇Keep clear the monitoring area (light axis) during initialization.
〇Sensitivity test must not be conducted during initialization. Make sure
that the Alarm Indicator of the Receiver finishes blinking before
sensitivity test.

Put the light obscuration filter test unit (NKL-F2), which is sold
separately, just in front of the lens of Receiver to perform Activation
/Non-activation test. Use the filters in the test according to the
following table.

Make sure that the Detector is activated within 30 seconds in
Activation test, and is not activated for 2 minutes in Non-activation
test, after placing the filter.

1. The Detector performs compensation process for the slow change
of received light intensity which is caused by the contamination of
the lens or shifting of light axis. In the monitoring condition, the
Detector regularly checks if light intensity received by the Receiver
is appropriate. If specified light intensity cannot be received,
compensation process is performed to compensate light intensity.
2. The Detector sends a fault signal (short circuit between K and C)
to the Remote Station, if the light intensity continues to be less
than 43% or more than 130% of the initial value for 12 hours or
more.
Cause of Fault
Countermeasures
Light axis is misaligned
Adjust the light axis and the receiving light
intensity.
(Refer to “Handling Instructions” on page 4)
Lens cover is contaminated
Clean the lens cover and adjust the
receiving light intensity.
(Refer to “Handling Instructions” on page 4)
〇 After readjusting the light axis and the receiving light intensity,
in order to update the internal status of detector, make sure to
restart the detector. Press and hold the reset switch of Remote
Station for 5 seconds or more, after the initial setting is completed
(i.e. when approx. 3 minutes pass after the Status Switch is placed
at the “NORM” position).
(If restarting the detector cannot be easily done, please wait for the
automatic update of internal status, which is performed 20 minutes
after the completion of initial setting)
The sensitivity of detector is compensated also if the received light
intensity is reduced to less than 50 % of initial setting value. If the
received light intensity continuously decreases, the Detector goes
into alarm at the specific sensitivity level.

The remote test function is supported by using Remote Station for
Beam Detector (LP04/ LP05) to connect the Detector to P-type
control panel. Test is remotely performed by operating the test
switch of the Remote Station. Refer to the Operation Instruction
Manual of the Remote Station for test method.

Fire alarm systems are essential for providing early detection and
warning in the event of fire in order to save lives and properties and
minimize damage. After installed, periodical maintenance is
necessary to keep the facilities in proper condition.
Important
〇Note in cleaning
Antifog coating is applied to both lenses of the Detector. For cleaning, gently wipe off
with a dry soft cloth to avoid damage. Do not use thinner or other solvents.
